Its True. Because Uni means more than one. Hope this helped :)
Answer:
Basing on explanations below;
1. Endothermic reactions have a positive enthalpy while Exothermic reactions have a negative enthalpy.
2. Endothermic reactions take place in high temperatures while Exothermic reactions take place in low temperatures.
Answer:
= 2.659 g NaCl
Explanation:
Molarity of a substance is given by the formula;
Molarity = moles/Volume in liters
Thus;
Number of moles = Molarity × volume in liters
= 1.3 M × 0.035 L
= 0.0455 Moles
But, the molar mass of NaCl is 58.44 g/mol
The mass of NaCl is therefore;
= 0.0455 g × 58.44 g/mol
<u>= 2.659 g NaCl</u>
intestinal flora
A modest level of ethanol enters the human circulation naturally from <u>intestinal flora,</u> equivalent to a fraction of a drink per day.
<h3>What is intestinal flora?</h3>
- inside the intestines are bacteria and other living things.
- They aid in food digestion.
- Intestinal flora produces vitamins like biotin and vitamin K. Also known as intestinal microflora, microflora, and gut flora.
<h3>Are intestinal flora good?</h3>
- Humans have 100 trillion viable bacteria in their intestines.
- The intestinal flora is the collective name for these living bacteria, which account for 30% of the faeces bulk.
- The intestinal flora contains both useful and dangerous microbes.
- They are evenly distributed and the good bacteria take center stage in healthy persons.
<h3>What purpose does the gut flora serve?</h3>
Intestinal microflora primarily serves two purposes:
- (1) metabolic processes that result in the absorption of nutrients and energy; and
- (2) host defense against invasion by alien microbes.
The immune system's development and balance depend heavily on intestinal microorganisms.
